Product Line Details: DFC Brake Rotor - Drilled and Slotted - Silver

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface. This design helps to reduce brake fade by allowing gases and dust to escape more efficiently, while the vented rotor construction improves airflow to maintain optimal temperature. The zinc silver hat finish adds corrosion resistance, extending rotor life especially in environments prone to rust.

Technical Specifications and Features

This disc brake rotor is vented and directional, with a surface that is both drilled and slotted to optimize braking performance. The rotor’s nominal thickness is 25 mm, with a discard thickness of 23 mm, ensuring safe replacement intervals. The rotor measures 320 mm in outside diameter and 48.5 mm in overall height, fitting precisely on Mazda 3 models. The zinc silver hat finish and rust-resistant coating protect against corrosion, while the 5-bolt hole pattern with a 114.3 mm bolt circle diameter ensures secure mounting.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mazda 3 vehicles
• Improves braking consistency under heavy use or high temperatures
• Reduces brake fade caused by gas buildup and dust accumulation
• Addresses rotor corrosion issues with rust-resistant coating
• Enhances brake pad bite and water dispersion in wet conditions

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 23 mm before installation. Clean the rotor surface to remove any protective coatings or oils prior to mounting. Verify the 5-lug bolt pattern and 114.3 mm bolt circle diameter match your Mazda 3 hub. Proper torque specifications should be followed to avoid rotor warping. It is recommended to replace brake pads simultaneously for optimal performance.
